Combined PET/MR systems: an overview and comparison of currently available options.

摘要: The integration of positron emission tomography (PET) and magnetic resonance imaging (MRI) in a combined PET/MR scanner is attracting much interest. With this new bimodal approach novel functional-anatomical multiparametric applications become feasible, which can be expected to deliver information beyond that accessible by separately applied modalities. Although the two technologies where initially regarded as inherently incompatible, different solutions have been developed implemented realise instruments for both small animal human imaging. present review first summarizes basic options possible designs. A chronological outline describes evolution from ideas, how PET MR might combined, over experimental systems recently realized industry. BrainPET/MR mMR Siemens Philips Ingenuity TF are characterised application examples provided illustrating features these instruments. Based on own experiences those reported publications number open issues discussed. Finally short comparative analysis status perspectives given.
